Hydrogen peroxide yog dab tsi?
Hydrogen peroxide feem ntau hu ua hydrogen peroxide. Cov tshuaj ntshiab hydrogen peroxide yog lub teeb ua kua xiav dej khov ua kua uas tuaj yeem tov nrog dej hauv ib qho kev sib xyaw. Nws yog ib qho muaj zog oxidant. Nws cov kua aqueous feem ntau hu ua hydrogen peroxide thiab yog cov xim ua kom tsis muaj xim thiab pob tshab. Nws cov kuab tshuaj tov yog tsim nyog rau kev kho mob qhov txhab kab mob, ib puag ncig kev ua kom huv thiab zaub mov ntxuav kab mob. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav yaj mus rau hauv dej thiab oxygen, tab sis tus nqi decomposition yog qeeb heev. Txoj hauv kev ceev nrawm rau cov tshuaj tiv thaiv yog ntxiv ntxiv catalyst-manganese dioxide lossis irradiate nws nrog luv hluav taws xob.
Muaj peb hom hydrogen peroxide rau kev kho mob, tub rog thiab kev siv. Cov dej tua kab mob niaj hnub yog kev kho mob hydrogen peroxide. Kev kho mob hydrogen peroxide tuaj yeem tua cov kab mob hauv plab hnyuv thiab ua rau pyogenic cocci. Nws yog feem ntau siv rau kev tua kab mob rau saum npoo av. Cov tshuaj hydrogen peroxide muaj cov nyhuv oxidizing, tab sis kev saib xyuas ntawm kev kho mob hydrogen peroxide yog sib npaug los yog qis dua li 3%. Thaum so rau ntawm lub qhov txhab mob, nws yuav muaj qhov hnov tsw thiab lub nplaim yuav oxidized mus dawb. Tsuas yog ntxuav nws nrog dej, thiab nws yuav rov qab los rau qhov qub tom qab 3 txog 5 feeb. xim! ! ! Thaum siv hydrogen peroxide rau kev tua kab mob, cov npuas dawb me me yuav tsim tawm vim tias hydrogen peroxide yuav yaj thaum nws ntsib hmoov av thiab plua av ntawm cov ntiv tes, decomposing los tsim dej thiab oxygen!
Lub luag haujlwm ntawm hydrogen peroxide
3% hydrogen peroxide feem ntau siv rau hauv kev kho mob rau qhov txhab lossis otitis media disinfection. Thaum nws ntsib cov tawv nqaij, qhov ncauj thiab mob ntawm qhov txhab, pus lossis av, nws tam sim ntawd ua rau cov pa oxygen. Qhov no ntawm cov pa atoms, uas tsis tau muab sib xyaw rau hauv cov pa oxygen, muaj lub zog muaj zog oxidizing. Thaum nws chwv nrog cov kab mob, nws tuaj yeem rhuav tshem cov kab mob thiab tua cov kab mob. Cov tshuaj ntxiv tom qab tua tus kab mob yog dej tsis muaj kuab lom los yog txob txob. Yuav tsis tsim kev ua qias tuaj ntxiv. Yog li no, hydrogen peroxide yog qhov tshuaj tua kab mob zoo tshaj plaws rau kev siv tshuaj tua kab mob. Tab sis tsis txhob siv cov tshuaj siab hydrogen peroxide rau cov tshuaj tua kab mob kom tiv thaiv kev kub nyhiab kom tawv nqaij thiab thaj chaw cuam tshuam.
Kev zoo nkauj ua kom zoo ntawm hydrogen peroxide
Hydrogen peroxide yog cov kua uas muaj ob lub pa oxygen atoms hauv ib qho dej qauv. Nws muaj cov permeability muaj zog thiab oxidation. Hauv cov tshuaj, hydrogen peroxide feem ntau siv los ntxuav cov qhov txhab thiab cov tshuaj tua kab mob hauv zos. Raws li kev tshawb nrhiav kawg, cov pa tshuaj hydrogen peroxide tsis yog ua rau cov khoom kho mob nkaus xwb, tab sis kuj tseem ua khoom zoo nkauj. Cov tawv nqaij ntawm lub ntsej muag nyob rau hauv qhov sib chwv nrog ib puag ncig sab nraud thiab feem ntau yog qias neeg los ntawm cov kab mob, cov plua plav, thiab lwm yam. cov kab mob, yog li cuam tshuam rau kev zoo nkauj ntawm daim tawv nqaij. Kev thov cov tshuaj hydrogen peroxide rau lub ntsej muag tsis tuaj yeem tsuas yog tshem tawm cov av ntawm daim tawv nqaij, tab sis kuj ncaj qha txhim kho cov kev ua ntawm cov xov txheej ntawm lub ntsej muag ntawm daim tawv nqaij, inhibit thiab oxidize lub deposition ntawm melanin, thiab ua kom daim tawv nqaij du thiab ywj. Txoj kev ua haujlwm: Tom qab ntxuav lub ntsej muag nrog lub ntsej muag kom huv, thov siv 3% hydrogen peroxide rau lub ntsej muag nrog phuam, 5 feeb txhua zaus, ib zaug ib hnub, 10 hnub raws li kev kho mob, thiab kev saib xyuas yuav tsum tau saib xyuas kom tiv thaiv hydrogen peroxide los ntawm nkag mus rau hauv lub qhov muag thaum lub sijhawm ua haujlwm. Tsis tas li ntawd, hydrogen peroxide kuj tseem muaj cov haujlwm ua kom pom cov xim plaub hau. Rau cov poj niam uas lawv cov plaub hau ntev dhau thiab cuam tshuam rau lawv cov tsos, tom qab piav qhia, thov siv cov tshuaj hydrogen peroxide ncaj qha rau ntawm daim tawv nqaij ib hnub ob zaug, kom plaub hau tsis ntev yav tom ntej. Nws ua xim dub thiab tuab, tab sis dhau los ua mos thiab xim yog lub teeb daj.
